PK57660: JAVA.LANG.CLASSCASTEXCEPTION FOR SAXPARSERFACTORYIMPL DURING CLUSTER START

Fixes are available

APAR status

Closed as program error.

Error description

The cause of the problem is that the thread context class loader
is set
to an application class loader that has overriden the XML parser
implementation.  The application code calls SIB, which calls SM,
which
calls EMF to read an XML document, which uses the incompatible
XML
parser implementation, which causes a ClassCastException.
